Glossary: |
1,8-cineole = 1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane
2-endo-hydroxy-1,8-cineole = (1R,4S,6R)-1,3,3-trimethyl-2-oxabicyclo[2.2.2]octan-6-ol |
Other name(s): |
P450cin; CYP176A; CYP176A1 |
Systematic name: |
1,8-cineole,[reduced flavodoxin]:oxygen oxidoreductase (2-endo-hydroxylating) |
Comments: |
A cytochrome P-450 (heme-thiolate) protein that uses a flavodoxin-like redox partner to reduce the heme iron. Isolated from the bacterium Citrobacter braakii, which can use 1,8-cineole as the sole source of carbon. |
